To compare the clinical efficacy of covered stents and bare-metal stents in the endovascular treatment of subclavian artery occlusive disease.
Between January 2014 and December 2020, 161 patients (112 males) underwent stenting of left subclavian arteries; CSs were implanted in 55 patients (34.2%) and BMSs in 106 (65.8%). Thirty-day outcomes, mid-term patency, and follow-up results were analyzed with Kaplan-Meier curves. Relevant clinical, anatomical, and procedural factors were evaluated for their association with patency in the two groups using Cox proportional hazards regression.
Mean follow-up was 45 ± 18 months. The primary patency was 93.8% (95% CI, 81.9%–98.0%) in the covered stent group and 73.7% (95% CI, 63.2%–81.6%;
Compared with bare stents, covered stents have a higher midterm primary patency in the treatment of subclavian artery occlusive disease.
